Description

4-[[2,6-Dihydroxy-3-[(4-Nitrophenyl)Azo]-5-[(7-Sulpho-1-Naphthyl)Azo]Phenyl]Azo]Naphthalene-1-Sulphonic Acid, Sodium Salt is a high-purity, complex azo dye intermediate essential for producing vivid and stable colorants. Its multi-azo structure provides exceptional chromophore strength and lightfastness, making it a critical component for demanding industrial applications. This compound is primarily required by manufacturers in the textile, ink, and specialty pigment industries seeking to formulate high-performance dyes with specific shade and durability characteristics.

Application

• Textile Dyeing: A key intermediate for synthesizing high-grade, wash-fast dyes for natural and synthetic fibers, particularly for achieving deep, complex shades.
• Ink Formulation: Used in the production of pigments for industrial inks, including those for packaging, printing, and specialty coatings requiring color consistency.
• Specialty Pigments: Serves as a precursor for creating complex organic pigments used in plastics, paints, and advanced materials where color stability is paramount.
• Research & Development: Employed in chemical R&D labs for developing novel chromophores and studying structure-property relationships in dye chemistry.
• Analytical Reagents: Can be utilized as a staining agent or colorimetric indicator in specific analytical and biological staining procedures.
